A laboratory set-up using an online vision system was designed to observe the dispersion behavior of glass and polyester fibers. The effect of different blend ratios, agitation speed, and dispersion time in dispersing “logs” and formation of “ropes”, was studied. Our results indicate that there is a specific dispersion time period in which optimum fiber dispersion can be achieved. This time was found to be shorter for glass fibers. It was observed that the dispersion behavior of each fiber type has a profound influence on the dispersion of fiber blends. It was also noted that there is an optimum agitation energy which allows the logs to be dispersed while minimizing the rope formation.
